As your cervix begins to efface (thin out) and dilate (open up), it may expel this mucus, and you'll notice discharge
that looks like egg white or mucus from a runny nose
on a cold day. You may even expel the plug in one gelatinous glob. This discharge might be tinged with a bit of blood.
When should I call my caregiver?
If there's a lot of thin, clear discharge, it can be hard for you to tell if it's just mucus or if you're leaking amniotic fluid.
